If Santisima’s surname sounds familiar, it’s probably because you remember his older brother, Jeo, a one-time junior featherweight contender who challenged Emanuel Navarrete for the WBO 122lbs title back in 2020. There are four boxing brothers in all, with David Santisima being a 6-1 (5 KOs) boxer who hasn’t fought since 2024. They all began boxing as children, trained first by their father, who worked on a copra plantation, harvesting the dried white insides of coconuts that would later be turned into coconut oil.
